Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to explain and apply fundamental concepts as linear and angular momentum, linear and angular impulse, moment of inertia, energy and work for a rigid body.
• be able to use the balance equations for particles and rigid bodies in plane motion
• be able to describe velocities and accelerations in Cartesian, polar and natural coordinate systems
• be able to formulate theoretical models for simple mechanical systems based on Lagrange´s and Hamilton´s methods
• be able to outline the most important result in the project work

Competences and skills
For a passing grade the student must

• starting with a real situation be able to delimit a problem and treat material bodies such as particles and rigid bodies
• be able to apply systematical methods to mechanical systems in motion
• be able to present written solutions to dynamical problems with suitable drawing of free body diagrams
• be able to formulate, describe and analyse a technical problem through text, equations and illustrations in a written academic report in the form of an article text. The report should include such elements as background, aim, purpose, execution, results and conclusions
• be able to present a written rapport with detailed description of the problem, made assumption, calculation and results

Judgement and approach
For a passing grade the student must

• evaluate the physical consistency of the obtained results
